Our customer continued to fail cleaning validation due to excessive bioburden readings and visual failures. We investigated and determined the root cause, which was poor piping design, low cleaning velocities, and dead-legs in the system.
Several options were presented for review; ultimately, the agreed upon method was designed and implemented. Post commissioning, cleaning validation passed successfully the first time.
We were contracted to perform a facility audit, followed by conceptual and detail design of a project to resolve the issues, as well as commissioning of the installed project.
